1990 diesel GMC 1500 Suburban radiator overflow?

[Lemmon man]

I have a 1990 GMC Diesel suburban and its leaking. im trying to find my overflow but i cant find it for the life of me. it has had problems lately. we replaced the fuel pump about 5 hoses and patched the radiator and the radiator repair was the last thing done and i got it back yesterday. so i don't thing it should still be leaking so i think its my overflow but i cant find it. if anyone if familiar with this model of GMC pls tell me where the overflow from the radiator is located.

Follow the hose near the radiator cap (the smaller one, not the large radiator hose that is at the top to the side). That will lead you to the overflow tank which is usually nearby.
